ADVERTISING DISPLAY MECHANISM.

Specification of Letters Patent.

Patented Nov. 26, 1912.

Application filed January 24, 1912. Serial No. 673,265.

To all whom it may concern.

Be it known that I, ARTHUR L. RUNYAN, a citizen of the United States,and a resident of Huron, in the county of Beadle and State of SouthDakota, have invented certain new and useful Improvements in AdvertisingDisplay Mechanism, of which the following is a specification.

Mly invention relates to advertising display mechanism and it is theobject thereof to provide a machine for displaying advertising matter inan attractive and novel manner.

Constructions embodying my invention are illustrated in the accompanyingdrawings, in which Figure 1 is a side elevation of the machine, partlyin longitudinal vertical section, and Fig. 2 is an end elevation of thesame, partly in transverse vertical section.

In the construction shown I provide a frame consisting of two tripodseach comprising three tubular members 1 which are provided at theirlower ends with anchorplates 2 and of which their upper ends are securedin the head-blocks 3. The anchorplates and the lower ends of the members1 are set in the ground so that the headblocks will be at equal levels.Mounted upon the head-blocks are suitable bearings 4c in which are journaled the trunnions 5 of a drum 6, which is preferably of theoctagonal form shown. At one end of the drum the same is provided with apulley 7 which may be connected by means of a belt 8 with a smallelectric motor 9, mounted as shown on the leg of one of the tripods, andwhich may be supplied with electrical energy when it is desired torevolve the drum. Passing radially through the drum are a number ofshafts 10 arranged so that a like number of the ends thereof emerge fromthe drum at each corner of the octagonal surface. The shafts arearranged circumferentially of the drum in groups in each of which theshafts are placed as nearly as possible equidistant from the ends of thedrum, the variation in longitudinal position of the shafts of any groupbeing merely such as to enable them to pass each other at the center ofthe drum. On the ends of each shaft are secured rectangular plates 11,the same being arranged so that at each corner of the drum there will bea row of the plates extending longitudinally and radially to the drum.On the portions of the shafts inside the drum each is provided at oneend with a collar 12 and at the other end has secured thereon 'a pinion13. For each longitudinally alined set of shafts the pinions are at theends thereof adjoining the same side of the drum, and for each of saidsets of shafts there is a longitudinally extending rack-bar 14 of whichone end extends through the end of the drum and is provided with aroller 15. Adjoining one end of the drum there is an upper fixedcam-plate 16 carried by a rod 17 extending up from one of thehead-blocks 3, and a lower fixed cam-plate 18 secured to the legs of thetripod. During the rotation of the drum the rollers 15 engage thecam-plates 16 and 18 alternately, being pushed inwardly by the uppercam-plate and pulled outwardly by the lower cam-plate, so that anintermittent longitudinal reciprocating movement is imparted to therack-bars.

With reference to the cam-plate 18 itshould be noted that the same is abar arranged tangentially to the circular path of movement of therollers 15, the ends of the bar extending outside said circular path andthe central part of the bar extending inside said circular path, whenviewed as in Fig. 2. As the rollers pass the bar they engage only theouter side of the central part of the bar so that said part of the barlies between them and the end of the drum.

Each rack-bar is provided with rack-teeth meshing with the pinions onalternate shafts, and adjoining the other or intermediate shafts thereare secured to the rackbars the rack-fingers 20 which have teeth meshingwith the pinions on said intermediate shafts, but on the sides of saidpinions opposite to the rack-bars themselves. Thus, at each longitudinalmovement of one of the rack-bars the alternate shafts of thelongitudinal set are turned in like directions while the other orintermediate shafts are turned in the opposite direction. The amount oflongitudinal movement given to the rackbars by the cam-plates 16 and 18is such that at each movement the shafts will be turned one-half arevolution so as to present to the observer the reversesides of theplates 11 carried by the shafts.

From the foregoing the operation of the mechanism will be apparent. Thedrum being actuated by the motor so as to run at a.

suitable speed, as each longitudinal set of the shafts reaches avertical position the shafts will be turned half of a revolution, eachadjoining pair of the shafts turning in opposite directions. Advertisingmatter of any kind may be displayed upon the surfaces of the plates 11and by suitable ar rangements of coloring, or by alternation of printedand pictorial matter upon the various plates the same may be made topresent to the observer a novel and attractive appearance, such that hewill be led to continue his observation at least until all of the plateshave been presented to view. An observer looking only at the uppermostrow of plates during one revolution of the drum will see both sides ofeach of the plates on the machine, since when a set of the platesapproaches the vertical position one side of them will be presented toView, and while passing the vertical position the plates of the set willbe turned so as to present to view the opposite sides thereof.

Now, having described my invention, what I claim and desire to secure byLetters Patent is:

1. In an advertising display mechanism, a drum revolubly mounted on ahorizontal axis, driving means for rotating the drum, series of shaftsextending radially through the drum, the shafts of each series lying ina plane extending longitudinally of the drum, means connected with theshafts of Copies of this patent may he obtained for five cents each, byaddressing the Commissioner of Patents,

each series for rotating them, and means for actuating said connectingrotating means.

2. In an advertising display mechanism, a revoluble drum, means forrotating the same continuously, revoluble shafts extending radially fromthe drum, the shafts being in longitudinally alined sets, plates carriedat the ends of the shafts, the plates of each set being alinedlongitudinally of the drum, a rack-bar for each set of shafts, and stationary cam-plates arranged to intermittently move the rack-barslongitudinally during rotation of the drum.

3. In an advertising display mechanism, a rotary drum, series of shaftsrevolubly mounted therein on axes radial thereto, plates carried on theends of the shafts, the shafts being arranged in sets alinedlongit-udinally of the drum, actuating means for rotating the alternateshafts in like directions and the adjoining shafts in oppositedirections, and means controlling said actuating means whereby each setof shafts will be rotated while passing through a certaln fixed plane.

In testimony whereof I have hereunto subscribed my name in the presenceof two witnesses.
